如何以编程方式设置listView的state_pressed颜色

Question

我(尝试做)编写没有xml文件的程序(android文档说它是可能的)但是我很难找到一些细节的信息.

当用中性色接触物品时,我想更换丑陋的橙色.有人知道我们怎么能在程序中做到这一点？对于没有R.loayout表示的ListView？

在此先感谢您的回答......

一些谈论:

  ColorStateList c = new ColorStateList( 
             new int[][] {
                     new int[] { android.R.attr.state_pressed},
                     new int[1]
                 }, new int[] {
                     Color.rgb(50, 50, 255),
                     Color.BLACK,
                 });

但是如何将其设置为我的列表视图？

列表视图的创建如下:

private class mybaseAdapter extends BaseAdapter {

    @Override
    public int getCount() {
        if (portList == null)
            return 0;
        return portList.size();
    }

    @Override
    public Object getItem(int position) {
        Log.v("getItem", portList.get(position).toString());
        return portList.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        Log.v("getView", portList.get(position).toString());
        return portList.get(position);
    }
}

    ListView lv = new ListView(context);
    TableRow.LayoutParams lp = new TableRow.LayoutParams(
            LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
    lv.setAdapter(new mybaseAdapter());
    lv.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            Log.v("onItemClick", "Clicked item is");
        }
    });
    addView(lv, lp);

您可以使用StateListDrawable创建它之后,可以将其设置为View with的背景v.setBackgroundDrawable(yourStateListDrawable);
